Find the missing side or angle.
Nina [5.8K]

Answer:

a=4.1

Step-by-step explanation:

The Law of Cosines is given as:

a^2=c^2+b^2-2cb\cos A.

Plugging in given values, we get:

a^2=4^2+2^2-2\cdot 4 \cdot 2\cos 78^{\circ},\\a^2=16+4-16\cos 78^{\circ},\\a^2\approx \sqrt{16.673},\\a\approx \fbox{$4.1$}.

A cab company charges $3 per cab ride, plus an additional $1 per mile driven. How long is a cab ride that costs $13?
Nadusha1986 [10]

Answer:

10 miles

Step-by-step explanation:

3+1x=13

Minus 3 from both sides.

3-3+1x=13-3

1x=10

Then divide both sides by 1.

1x/1=10/1

x=10
